The COVID-19 outbreak has caused an indeterminate number of deaths and how many days it will take to get the situation under control is indeterminable.
Indeterminate and indeterminable are the words of English that are not used commonly. Both terms are as confusing as they sound. Both are adjectives and contain the root ‘determine’ which means to establish something. The only difference is the suffix “able”. You can understand it in the following way:
Indeterminate is “undefined or unfixed”, while indeterminable is “not able to define or unable to fix”.
Here’s an example to showcase their meanings:
Indeterminate number of meteors hit the earth recently. It is indeterminable when the next group of meteors will bombard the earth with such destructive power.
Let’s have a look at the exact definitions and some cases to make both terms clearer.

Definition of Indeterminable
Indeterminable means inability to decide, unable to fix something, or uncertain in nature of something. There should be no difficulty in the pronunciation as it is pronounced as “in-de-ter-min-able”. Indeterminable is taken from the Latin root word “indeterminabilis” and was used for the first time in the late fifteenth century. This word was used broadly in the early 1900s. Indeterminable has 3 root words; “in” means “not”, “determine” means “to establish/explain/ascertain something”, and “able” means “ability/capability”. Simply put, indeterminable is not having the ability to explain something.
Example sentences of indeterminable

In this sentence, indeterminable was used in the meaning of an unknowable amount. When the girl drank a large amount of Vodka, she got admitted to the hospital.
The concept of both words is very easy to grasp. Although these terms can be used interchangeably, it is not recommended as both words have considerably distinct meanings. There’s a little trick here to understand and remember the terms. Remember the suffix “able” at the end of indeterminable, you can associate it with incapable and remember that something is indeterminable when you are incapable to define it. Finally, something indeterminate is simply undefined.
